what is an equation of the line that passes through the points (-6,2) and (6,-2)

Answers

Answer:

y = -1/3 x + 8/3 or 3y = -x + 8

Step-by-step explanation:

m = (-2 - 2) / [(6 - (-6)]

= -4 / 12

= -1/3

Use (-6, 2) and substitute in the formula:

y = mx + b

2 = -1/3 (2) + b

2 = -2/3 + b

2 + 2/3 = b

8/3 = b

y = mx + b

y = -1/3 x + 8/3 or 3y = -x + 8

Sara is selling tickets to a high school festival. She sold 10 less senior tickets than junior tickets and she sold 3 times as many sophomore tickets as junior tickets (no freshman allowed). Senior tickets cost $3, junior tickets cost $5 and sophomore tickets cost $7. Sara raised $782. Write an equation to model the situation so that we can find the amount of tickets sold to seniors, juniors, and sophomores.

Answers

Answer:

[tex]29x-30=782[/tex] where x denotes number of junior tickets.

Step-by-step explanation:

Let x denotes number of junior tickets.

Sara sold 10 less senior tickets than junior tickets.

Number of senior tickets [tex]=x-10[/tex]

Sara sold 3 times as many sophomore tickets as junior tickets.

Number of sophomore tickets [tex]=3x[/tex]

Senior tickets cost $3, junior tickets cost $5 and sophomore tickets cost $7.

Total amount raised by Sara [tex]=5x+3(x-10)+7(3x)=5x+3x-30+21x=29x-30[/tex]

Sara raised $782.

So,

[tex]29x-30=782[/tex]

Nilda has $250 in her savings account. She plans to save $15 per week from her salary. Iona has only $200 in her account but can save $20 a week from her paycheck. How many weeks will it take before the amount in each savings account is the same?

Answers

Answer: 10 weeks

Step-by-step explanation:

Nilda's money = 250 +15x being x the number of weeks that have passed    

Lona's money= 200+20x

If they have the same amount, then

250+15x=200+20x

250-200=(20-15)x

50=5x

50/5=x

10=x

Answer:

10 weeks

Step-by-step explanation:

Nilda's money = 250 + 15x

Lona's money = 200 + 20x

250 + 15x = 200 + 20x

250 - 200 = (20 - 15)x

50 = 5x

10 = x

Alonzo earns 8% commission on vacuum cleaner sales. This past month, Alonzo sold 70 units at $150.00 each. How much did Alonzo make in commissions for the past month?

Answers

Answer:

$840

Step-by-step explanation:

First, multiply 70 by $150 to get the total amount the Alonzo earned

70 x 150 = 10,500

Then, multiply 10,500 by 1.08 to find the total amount made with commissions.

10,500 x 11,340

Finally, subtract 10,500 from 11,340 to find the amount of money earned from commissions.

11,340 - 10,500 = 840

Answer:

$840

Step-by-step explanation:

Start by finding the total profit made:

70 • $150 = $10500

Then multiply the total by the commission rate, %8, which is equal to 0.08:

$10500 • 0.08 = $840

The answer is $840

Plz mark Brainliest

Answer:

x=−8

Step-by-step explanation:

Let's solve your equation step-by-step.

−6=3/8x−2+

1/8x

Step 1: Simplify both sides of the equation.

−6=3/8x−2+1/8x

−6=3/8x+−2+1/8x

−6=(3/8x+1/8x)+(−2)

(Combine Like Terms)

−6=1/2x+−2

−6=1/2x−2

Step 2: Flip the equation.

1/2x−2=−6

Step 3: Add 2 to both sides.

1/2x−2+2=−6+2

1/2x=−4

Step 4: Multiply both sides by 2.

2*(1/2x)=(2)*(−4)
